What's the use case for homebrew on Linux these days? Most distributions have their own package manager, which you almost always end up using anyways, so already you're adding an extra package manager. Besides that, most of the community isn't using homebrew, so clearly won't have "more" packages, and the packages it'll have will be less reviewed than the ones in your distribution. I can't really see any point to use homebrew on Linux except "I used to use it on macOS", which doesn't feel that strong of a use case really.
